1. the benefits of synthetic vs conventional in an engine oil do not
translate at all well to ATF. Beware over-generalizing. (Not to mention
over-reacting [to Volvo's recommendation].)
2. Back before Dexron had attained its current level of anti-oxidation
properties, back before torque converters locked up, (ie, 20+ years ago),
the recommended interval for changing ATF was 25K miles. Many of the first
FWD cars failed to sufficiently cool their ATF. But this is not true of my
850. Intelligence dictates that I modify/discard old concerns once they no
longer pertain...
3. I used to change my ATF every 25K miles, too. But times (and
technology, and ATF) has changed (improved drastically) since then...
4. My 850 has plenty of cooling capacity, so my ATF does not see extreme
high temperatures, so it doesn't burn up. In fact, if the ATF does burn
up, it's not the ATF's (nor, likely, the owner's) fault, nor would fresher
ATF have prevented the problem.
5. Superstitious behavior often makes us feel better. Keep scaring those
elephants away...
